Triclopyr BERMUDA SOD HELP!

SITUATION

- Mixed Ortho Weed B Gon Chickweed, Clover & Oxalis Killer concentrate in with generic 41% glyphosate by mistake and sprayed on bare soil (I read another thread where someone mentioned including the Weed B Gon etc.).

- This was done to kill existing left over common Bermuda post sod removal. The plan is to install hybrid Bermuda sod in about 2 weeks time.

QUESTIONS:

1). Will the active ingredient in the Weed B Gon (Triclopyr etc.) still be present in the soil in two weeks time and injure/kill the new bermuda roots/sod?????

2). Is this product like glyphosate where you can spray and lay sod a day or two (ideally 7) later?

3). Can the Weed B Gon be "flushed" out?

ACTIVE INGREDIENT:
Triclopyr , Triethylamine salt* 8%
*5.74% Triclopyr acid equivalent (0.49 lb/gal)

Thanks everyone!

Thanks for the replies! Follow-up question:

Do you think it is better to let it sit on the surface and breakdown from sun light or to hit it with a hose in an effort to wash it down into the soil/dilute it?

Does either make a difference?

Thanks again!

I found three articles that help to shed light on how long triclopyr stays in the soil and also if it is absorbed via roots.

How applicable they are to sodding... ???

It seems Triclopyr hangs around in the soil longer and can have some root uptake - compared to glyphosate.

I think with the existing sprayed triclopyr spending 10 days in the sun and watering to stimulate old Bermuda growth, before a second round of glyphosate - combined with Bermuda being a descent spreader to fill in any patches that don't make it at the time of sodding, things will be ok.

Thanks to those who replied and hopefully this thread will be of use to someone else.

:p
